My wifi seems to disconnect from my wifi when the screen turns off, despite me having changed my settings to never sleep. When I look at the wifi settings it says "Unsuccessful Connection". I didn't have this problem with my MT3G.
Anyone having similiar issues or a fix?
wifi Reconnection issues
I'm having the same problems with mine.
It initially connects to wifi fine but when the screen goes off it sometimes drops the connection and will not reconnect without a reboot.
I have tried setting it to keep the wifi when sleeping but it makes no difference.
I found a few similar reports elsewhere and followed most of the suggestions, like changing routers, changing wifi channels, setting an IP address instead of DHCP etc. Nothing seems to make any difference so far.
Mine never seems to reconnect after waking up, but I just go into the Wireless settings/Wifi settings window (where it lists all the Wifi networks in the area) and press on the network name and it brings up a dialog allowing me to connect again. I press the Connect button and it instantly reconnects. No reboot required...
Try increase your router's "Group Key Update Interval". I had the same problem with my D-Link DIR-655. I changed mine to 10 hours and it's working fine for me now.
i have the issus that my wifi is "connected" i mean i see the logo at the top bar but after a few minutes i don't get any update from the internet like gmail oder twitter when is wake up the device from sleep i get them back again
maybe it something with the Group Key Intervall but i can't switch it on my speedport w700v router
I just tried switching mine, highest it can go is 7200 seconds, so I bumped it to two hours instead of one. linksys
my wifi reconnects when I wake the screen almost 100% but it's not reliable.
I have to go to wifi list and reconnect. Sometimes I disable wifi and then re enable, conects no problem. Irritating
i heared that switching the encryption from wpa/wpa2 to only wpa2 will solve this issues, will try it when i am at home
...seems like almost everybody got this problem.
for example with my Hero i don't had this problems so it's something with the W-Lan card of the Nexus
Got this problem too but will try the suggested work arounds when I get home tonight
found out that my encryption is wpa2 not wpa/wpa2 ... damn so thats not the reason
and my router cant configure the group key intervall
I don't have this issue, running CM5.0.3.1, mine is set to Never Sleep and it does not. My connection does not time out either. I connect to two Trendnet TEW-637AP's at home, in mixed b/g/n mode with WPA2-PSK mode security.
Could it be, that this prob exists just for nonrooted phones?!
i've got mcr 1.6 which is rooted and don't work
i think it's a problem with the wifi card and the wifi router
rooting just means that you get read/write access to all folders
doesn't change anything on your wifi connection

Click to expand...
Click to collapse
Not exactly, it means also modified system files, which could include those that interface with the wifi chip and those that control the sleep state of the device.
Also, Cyanogen (and most other custom roms now) are running on a different (newer) kernel.
yes i know
but mcr is although running on different kernel and it's not working there
i don't think its an issue bei the stock rom and mcr
maybe here is someone with CM where the wifi drops?
edit:
okay i tried it with the desire rom version from modaco, the same failures, maybe i try a CM built now, and see if it changes
Code:
[B]Rom [/B] [B]Router / Access Point[/B]
MCR 1.6 | Speedport w700v | not working
Desire MCR | Speedport w700v | not working
CM 5.0.3.1 | Speedport w700v | not working
i think this means it's not a rom issue, its something with the routers and access points in combination of the wifi card from the nexus
That´s strange..perhaps just accidentally, but: yesterday I installed "Task Manager" , which has an auto-kill function.....since then my Wifi reconnects perfectly
maybe because it automatically does anything inside of the 10 minutes which keeps the wifi active?
which one did you install?
there are a lot of them on the market
which developer?
edit:
ah i found a strange issue, today i was at the wifi of my girlfriend, she has the same router BUT i don't have the wifi problems there, with the same model of router thats very strange
i found another work around, i set my twitter client to 5 minutes update intervall, this means every 5 minutes is network traffic and the connection won't drop after my 10 minutes public key intervall change
don't know how much battery is used while setting from 10 to 5 minutes but i think it should be okay
Try a different WiFi channel
I've seen reports of WiFi connection problems being solved by changing channels on the AP. Channel 10 seems to be a consistently reliable choice.
I just installed CM7 a3.5 and everything would be great if I could just get the wifi to work right. It will work fine for a while and then it will start to cycle "Scan, Connecting, Disconnect" over and over again. Rebooting doesn't help. It isn't a signal strength problem because when it does connect I get full bars and the router is about two feet away. Also, it works fine when running webOS.
edit: found the thread about wifi problems and got it working by switching router's wifi channel.
I posted my solution on another thread. You may find it helpful:

Hi folks
Since I updated to JellyBean (JellyMod currently) I have an issue with my wifi connection.
It shows connected but i cant transfer any data (every app fails to establish a connection) until I turn off the wifi and turn it on again. then it ill work for some time and fails again after a not defined period of time.
I found a lot of threads regarding similiar problems but I did not find a solution yet (and for me having a rooted phone installing an app that that runs in background like wifi fixer is a workaround, not a fix
I already did a complete factory reset and fresh install of jellymod.
My router at home is a netgear wndr3700 with the latest dd-wrt. all my other devices work great.
I set the wifi of my i9070 to always on. also i installed auto wifi for location based wifi on/off-profiles.
all of this worked with gingerbread, never had problems...
any idea? seems like a lot of galaxy phones and even tabs are affected...
Thanks in advance!
So I have a rather odd problem, I installed Nightmare ROM (4.3), and it seems to work great, with the exception that if I connect to wifi, all my other devices lose the wifi signal.
As soon as I turn off the wifi on my note, my laptop and desktop connect fine to the router.
Any ideas / suggestions?
I found this https://code.google.com/p/android/issues/detail?id=58493 but it has nothing informative in it.
So i have ViperOne 4.1.0 running with Elemental X 10.8 kernel for over a week now. Everything was working fine up until yesterday when suddenly my phone cannot get an external IP address on my Wifi at home anymore. It connects fine to the Wifi itself however it cannot get any internet connection.
I have reset my router, modem, phone and nothing has worked. Other devices in my home which connect to the same wifi get internet connection just fine only my HTC One does not. Mobile data connection works fine btw.
Whats really puzzling to me is that really i have changed nothing on my phone in the last couple of days and not all of a sudden its simply not working so i'm grasping at straws here...
Anybody experiences similar issues or have any ideas what else i could still try to fix this?
Thanks
Well it turns out that changing the Wifi channel on the router from auto (was actually 9) to 11 in my case solved the problem. Weird ****...
